Pressure gas container

Abstract

A pressure gas container of a predetermined volume for the storage of hydrogen on the basis of a gas/solid reaction and which is filled with a storage material, characterized in that at least one compressible impervious elastic element is enclosed within the storage material and is adapted to have its volume compressed by a pressure action by the storage material.

I claim: 
     
       1. A pressure gas container of a predetermined volume for the storage of hydrogen on the basis of a gas/solid reaction and which is filled with a storage material, characterized in that at least one compressible impervious elastic element is enclosed within the storage material and is adapted to have its volume compressed by a pressure action by the storage material (1) and which is made of a material which is stable at the temperatures occurring when the pressure gas container (3) is charged with hydrogen and discharged said elastic element being so embedded in the storage material and the container volume is completely filled with the storage material when in a gas charged and discharged state. 
     
     
       2. A pressure gas container according to claim 1, characterized in that a plurality of elastic elements (2) are embedded in the storage material. 
     
     
       3. A pressure gas container according to claims 1 or 2, characterized in that each elastic element (2) is hollow. 
     
     
       4. A pressure gas container according to claim 3, characterized in that the outer walls of each elastic element is of metal material. 
     
     
       5. A pressure gas container according to claim 3 or 4, characterized in that each elastic element is filled with a medium which is liquid under the conditions of pressure and temperature corresponding to charging the pressure gas container with hydrogen and gaseous under the conditions corresponding to discharging the pressure gas container. 
     
     
       6. A pressure gas container according to claims 1 or 2, characterized in that each elastic element is constructed of form plastic material with closed pores. 
     
     
       7. A pressure gas container according to one of claims 2-6, characterized in that the elastic elements are in a random arrangement. 
     
     
       8. A pressure gas container according to one of claims 1-6, characterized in that the elastic elements have an elongated extended form, are aligned parallel to the longitudinal axis of the pressure gas container (3), and their length corresponds to the length of the pressure gas container. 
     
     
       9. A pressure gas container according to claim 2, or according to claim 2 and one of claims 3-6, characterized in that the elastic elements (2) are constructed as disc-shaped elements with a cross sectional form corresponding to the cross section area of the space between the inner surface of the wall (5) of the pressure gas container (3) and the outer surface of a gas tube (4) coaxially positioned on the interior of the pressure gas container and are spaced from one another along the axis of the pressure gas container. 
     
     
       10. A pressure gas container according to one of claims 1-5 or 8-9, characterized in that the elastic elements (2) are formed at least in their surface region of a material having high thermal conductivity. 
     
     
       11. A pressure gas container according to claim 10, characterized in that the elastic elements (2) have external flat prolongations (6) which abut and extend along the inner surface of the wall of the pressure gas container (5). 
     
     
       12. A pressure gas container of a predetermined volume for the storage of hydrogen on the basis of a gas/solid reaction and which is filled with a storage material, characterized in that at least one compressible impervious elastic element is enclosed within the storage material and is adapted to have its volume compressed by a pressure action by the storage material (1) and which is made of a material which is stable at the temperatures occurring when the pressure gas container (3) is charged with hydrogen and discharged, said elastic element being so embedded in the storage material and the container volume is completely filled with the storage material when in a gas charged and discharged state; further characterized in that a plurality of elastic elements (2) are embedded in the storage material;   further characterized in that the elastic elements (2) are constructed as disc-shaped elements with a cross sectional form corresponding to the cross section area of the space between the inner surface of the wall (5) of the pressure gas container (3) and the outer surface of a gas tube (4) coaxially positioned on the interior of the pressure gas container and are spaced from one another along the axis of the pressure gas container.
